Subject: crash with 6.7 rc2 and rc3


lenovo laptop boots fine under 6.7rc1 and older including 6.6.2 stable.
but not for 6.7 rc2 or rc3.

It has a intel 7260 (rev 3) wireless and :

cpu family	: 6
model		: 60
model name	: Intel(R) Core(TM) i7-4800MQ CPU @ 2.70GHz
stepping	: 3
microcode	: 0x28


As of 6.7 rc2 / rc3 it crashes towards the end of boot bringing up 
services -  some parts of crash scrolled off the screen so I apologize 
if this (manually transcribed) trace didn't catch the first part.

I did a git bisect between rc1 and rc2 but was unable to reproduce the 
crash for some reason. (I did not do make clean between each bisects).

During the bisect it booted every time, but networking was not 
functional for any of the bisects.

Hope it's okay to report even though git bisect didn't get anywhere.

This is the what I got from screen :
